Wema Water or Fuel Level Sensor S3 225 mm 12/24 V

Product description:

The Wema S3-A225 water or fuel level sensor with a length of 225 mm is a precise measuring device designed to monitor liquid levels in tanks, suitable for both water and fuel applications. This product is widely used in boats, yachts, specialized vehicles, construction machinery, and industry where constant monitoring of operating fluid quantities is essential. The sensor operates on a resistive principle – changes in liquid level cause a change in electrical resistance within the range of 240–30 Ohms, allowing accurate readings by compatible analog gauges. The sensor is mounted vertically, usually at the top of the tank, using a standard mounting flange with a gasket, ensuring tightness and leak resistance. The housing is made of corrosion-resistant materials such as stainless steel and high-quality plastics, guaranteeing long service life even in harsh environmental conditions, including exposure to seawater or fuels. The sensor is universal in terms of power supply – it supports 12 V and 24 V, allowing use in most vehicle and industrial installations. Thanks to its compact design and 225 mm length, this model is suitable for tanks of small to medium depth, providing quick and easy installation and reliable operation over a long period.
